Our invention-relates to a product known as packagedyes for home use, and particularly to an improvement on the dye disclosed in several prior patents, relating to a combina tion of dye and soap, one of which is No.

1,610,291 dated December 14, 1926.

In theproduction of dyes of the character mentioned, the manfacturer is confronted with the problem of preparing a product that no will enable the user to produce results that will equal or approximate the results obtained by a commercial dyeing house. This problem is difficult because in the commercial dyeing establishments the work is done by experts 5 who have at hand the proper dyes, mordants, fillers, penetrators and mechanical equipment.

Inasmuch as the individual buyer cannot be trained or educated to perform the operations in a skillful manner, the product should be so prepared that it will be, in eflect, foolproof; in other Words, a product that will except under unusual or abnormal conditions insure-satisfactory results. Such a dye should contain proper dyes in correct proportion and mixture, together with the necessary dye as-' sistants such as mordants, fillers, diluents and penetrators.

We have found that when a roduct is made which consists of the proper yes, the necessary fillers or mordants, such as common salt, Glaubers salt or starch; the necessary diluents and solvents such as water-and alcohol, together with a percentage of alkylatednaphthalene sulphonic acid or its salts, or 1n general a sulphonic acid salt of an alkylated polynuclear hydrocarbon, the product 1s eminently satisfactory for home use. It results in a preparation having a high degree of solubility, excellent penetrating effect, evenness of shade and softness of fabric, and enables home dyeing with practically perfect results.

Referring to the alkylated polynuclear hydrocarbons, and especially to the alkylated naphthalene sulphonic acids, their use is especially recommended on account of their hi h wetting power.

stitute for soap, but they not only substitute for soap but are useful in reducing the surface tension of liquids, and increase penetration. The manufacture of some of these compounds is described in the German Patent No. 336,558, one of which especially described consisting in treating naphthalene with sulphuric acid and afterwards condensing it with iso-propyl-alcohol. method is described inEnglish Patent No. 302,258 and quite a number of diflerent products are described.

They all consist in sulphonating naphthalene or a polynuclear hydrocarbon of, the aromatic' or hydro-aromatic series and then condens ng them with an aliphatic, aromatic-aliphatic and hydro-aromatic alcohol, or in general, a compound containing an alcohol group. It is essential that the alcohol has at least three carbon atoms, methyl alcohol or ethyl alcohol will not give it the wetting properties. On the other hand, iso-propyl alcohol or butyl alcohols, or butylene' glycol are eminently satisfactory. Also, ethylene glycol-monopropyl ether can be used. Also cyclo-hexanol, benzylalcohol, and the like. The side chains may also link together two aromatic nuclei as is the case, for instance, in thecondensation products of formaldehyde with naphthalene sulphonic-acids, as expressed in the U. S. Patent No. 1,722,904. The said .sulphonic acids A little different Y may also contain'other substitutents such as halogen atoms or nitro or amine or hydroxyl groups and the side chain may also be attached to such substituents as for example in amyl-naphthylamine sulphonic. acids may be employed in the state of free acids or of salts.

The actual chemical composition of these compounds is not known exactly; Dr. A. Laudolt in Melliand, vol. 9, page 759 describes the condensation product of sulphonated naphthalene with iso-propyl alcohol with the following graphic formula:

1 CH OH:

SOgNB On the other hand, in the book by Curtis, Die Pigment Farbstofien page 16, the formula is given:

CHr-OH-OH:

SOzNa Forthis reason we shall refer to those compounds merely as alkylated' polynuclear hytechnically perfect way of dyeing materials which they themselves could never achieve without knowing :the properties of different wetting materials \as related to the dyes, and without knowing the proper proportions in order to obtain the best results.

By using our composition of matter in which we select the right type of dye and combine it with the righttype of wetting agent, a composition of matter is obtarned that can be used by any layman directly, without any technical knowledge whatsoever by simplyplacing the composition of matter into the proper solvent or suspending agent, like water, then treating the desired artlcle 1n it by immersion, and, if necessary, heating for a length of time required until the proper shade of color is obtained, then taking it out, drying and pressing it.

The composition of matter can be produced either in solid form, such as cakes that are easily soluble in water, or in the form of a paste, or liquid in solution, depending upon the nature of the market and the nature of the product to be dyed.

A few examples of combinations that will give the desired result are as follows:

1. 21% direct black, C. I. 581, 10% isopropyl naphthalene sodium sulphonate, 69% common salt.

- 2. 1% of alkali blue, C. I. 70.4, 2% of isoprop-ylated naphthalene potassium sulphonate, 97 Glaubers salt.

3. 5% of cyanone blue, 5R, C. I. 289, 5% direct blue BB, C. I. 406, 8% of iso-propylated naphthalene ammonium sulphonate, 2% sulphonated soap, 80% common salt.

4. 1% of acid violet, 3B, C. I. 698, 1% of iso-propyl naphthalene sodium sulphonate, 97% water, 1% soap.

5. 3% methylene blue, C. I. 922, 1% of butylated naphthalene ammonium sulphonate, 25% alcohol, 71%. water.

6. 6% methylene blue, C. I. 922, 12% buty I lated naphthalene ammonium sulphonate,

gum arabic, water.

7. 50% rhodamine B, C. I. 749, 50% aniylated naphthalene potassium sulphonate.

. 8. 33% alizarine blue,C. I. 1054, 15% iso-- propylated naphthalene sodium sulphonate, 15 sulphonated soap, 10% ammonium sulphate, 27% common salt.

9. 2% cosine, C. I. 768, 2% iso-propyl naphthalene sulphonic acid, 48% alochol, 48% Water. p In these examples, we have shown a few of many possible variations. The difierent chemicals and dyes can be interchanged, their quantities varied, the product substituted by equivalents, and the finished product may be in liquid, solid or paste form.

Instead of dyes mentioned above, any other d ves of commerce or mixtures thereof, that will furnish the results required can be substituted. Instead of ordina salts like Glaubers salts, other salts lie chromium or chromate salt can be used.

We claim:

1. A composition of matter adapted to be dispensed in packages and to be combined with a liquid for use, comprisingsulphonic acid salt of an alkylated polynuclear' hydroear bon residue possessing a high wetting power, and a water soluble dye.

2. A composition of matter adapted to be dispensed in packages and to be combined with a liquid for use. comprising a water soluble dye and a sulphonic acid salt of a substi 'tuted polvnuclear aromatic hydrocarbon possessing high wetting power.
